D, thanks for replying to my problem.
I contacted Rhino and they told me to just reconfigure the T1 line and
it appears to fix the problem.
My question is as we made zero changes to the channel bank, why do we
have to reconfigure it to get it to work?  Do you need to reconfigure it
every now and then?
